That comment is a strong sign that this was AI-generated. LLMs have the tendency to leave superfluous comments even when the code is self-explanatory. In this case, strconv is a well-known stdlib package, and anyone reading this in their IDE would get the documentation for what it does. In fact, all of the comments in this function and in most of the file are redundant, and I would point this out in a code review.

But, of course, this was vibe coded, so it's unlikely a human actually reviewed it.
